The Audible audio book service stores digital copies of audio books using the AA file extension. A division of Amazon is Audible. The Apple iPod and Amazon Kindle are only two examples of devices that can play AA files. Nevertheless, the majority of digital audio players do not support the format. To listen to the audiobook with Windows Media Player, for instance, a conversion to a more appropriate audio format, like MP3, is necessary. Since its debut, the AA file format has been enhanced, giving rise to the AAX file extension.
Although they are within the category of audio files, AA files have specific characteristics that set them apart from MP3 or WAV files. Aside from the actual auditory data, AA files may also include other data like as bookmarks and chapter markers. Three alternative formats, ranging from 8 kbit/s to 32 kbit/s, can be used to save AA files. As a result, the audio quality depends on the bitrate and can be anything from MP3-like to AM radio-like. DRM protection in AA files makes it impossible to convert them into a more popular audio format.
